Problems solved by technology

The temperature and humidity of the external environment are different in different periods of time, and the corresponding enthalpy values ​​are also different. The temperature and humidity setting of the air conditioner is a fixed value according to the spring, summer, autumn and winter modes. The temperature and humidity are controlled by a single point and cannot be changed according to changes in the external environment. The energy consumption of the whole system is very high, and the energy waste is relatively large

Embodiment Construction

[0056] The preferred embodiments of the present invention will be further described in detail below.

[0057] An energy-saving control method for an air conditioner, comprising:

[0058] According to the set temperature control range and humidity control range, calculate the enthalpy value range and moisture content range, on the psychrometric chart, according to the calculated enthalpy value range and moisture content range, based on the principle of the minimum enthalpy value change, combined with The isenthalpy line divides the environmental state into several different zones, and each zone corresponds to at least one control method;

[0059] A temperature and humidity detector is installed near the air inlet of the air conditioner to automatically detect the ambient temperature and humidity in real time. According to the temperature and humidity detected by the air inlet of the air conditioner, the real-time enthalpy and humidity are calculated and matched with the multipl...

Abstract

The present invention provides an energy-saving control method and control system for an air conditioner. The energy-saving control method for an air conditioner includes: calculating the range of enthalpy and the range of moisture content according to the set temperature control range and humidity control range. Based on the calculated enthalpy range and moisture content range, the environmental state is divided into several different zones based on the principle of the minimum enthalpy change, and each zone corresponds to at least one control mode; Temperature and humidity, calculate real-time enthalpy and moisture content, and match it with multiple zones divided on the psychrometric chart in real time, and control according to the control method corresponding to each zone. Adopting the technical scheme of the present invention, the temperature and humidity control of the air conditioner is converted from point control to range control, and the average energy consumption is reduced by about 30%, which truly realizes the real-time matching between the control temperature and humidity points and environmental energy, and realizes intelligent energy-saving control , the control method has low investment, simple equipment modification and easy implementation.

Description

technical field [0001] The invention belongs to the technical field of air conditioner control, and in particular relates to an air conditioner energy-saving control method and control system. Background technique [0002] At present, domestic industrial air conditioners for painting are required to meet a certain temperature and humidity. The control mode is basically single-point control, that is, a fixed temperature and humidity are set within a certain period of time, and then the heating, humidification, surface cooling, etc. are controlled by the program to achieve the set temperature. Temperature and humidity to meet the field use. The temperature and humidity of the external environment are different in different time periods, and the corresponding enthalpy values ​​are also different. The temperature and humidity setting of the air conditioner is a fixed value according to the spring, summer, autumn and winter modes. The temperature and humidity are controlled by a ...
